An impression of the relative relief of the land is given here by interlined brushwork ('hachuring'). The hachuring is dense in high areas, except the summits of hills, which are left bare. Settlements are described by red blocks. One major feature of the Survey is the attention paid to the road network, an important military factor. Here pinpricks can be seen along the roads, showing that a mechanical instrument was used to plot them. Major roads are tinted yellow.
